Choline is a nutrient related to the water-soluble B-complex vitamins that is necessary for the structure and function of all cells. It is important for the structural integrity of cell membranes and proper functioning of the brain, as well as required for a number of metabolic reactions that take place in the body. Humans can synthesize choline themselves, or they can consume choline through the diet. It can be found in high amounts in foods such as egg yolk, peanuts, fish, milk and a variety of meats and vegetables. Dietary choline is absorbed from the small intestine and travels through the bloodstream to all organs and tissues of the body 1.
